Iran ceasefire teeters amid strikes

The diplomatic breakthrough brokered by Pakistan faced a swift reality check as Israeli forces launched their heaviest bombardment of Beirut to date, killing over 250 people in a single day.

Iran has condemned the strikes as a grave violation of the truce terms, while the White House maintains that the agreement never extended to operations in Lebanon.

The impasse is further complicated by Tehran's continued chokehold on the Strait of Hormuz, where shipping remains virtually paralyzed despite the deal.

Negotiators from both sides are scheduled to meet in Islamabad this weekend for high-stakes talks to salvage the fraying agreement.
